Example 2: There is a controllable fan with a capacity of 4000 m3/h and
two non-controllable fans each with a capacity of 3000 m3/h.
The percentage of controllable ventilation is 4000 / (4000 +
3000 + 3000) = 40%. Enter the value 40 at OUT.16.
The first extra fan activates based on the calculated
setpoint thermal control. The second according to:
calc. Setp.Th.Ctrl. + (calc. Setp.Th.Ctrl. – Calc.startTVent - Calc.
Bandwith)
Total capacity
Air inlet = 100%

Enter the air inlet position, as it should be at 40% total
ventilation (controllable maximum ventilation) at SYS.12.
These extra fans are activated as soon as the temperature rises above
the Required value thermal control + Hysteresis. The control will
remain active until the measured value equals the required value. A
Control time can also be set here.
